Patented Jan. 18, 1949 TROLLEY WIRE HANGER Samuel S. Matthes, `Manseld,Ohio, assignor to The Ohio Brass Company, Mansfield, Ohio, a corporationof NewJersey t Application octber 19, 1945, seriaiNo. 623,216

5 Claims.

My invention relates to supports for trolley wires and has particularreference to those de` vices for supporting trolley wires forming a partof the overhead system for trolley bus operation.

In such systems the parallel trolley wires are placed some 18 to 24inches apart and of opposite polarity. This requires suflicient andproper insulation between the wires which is one object of my invention.

Another object is to provide means for attaching supporting spanwires tothe device and which means is adjustable to compensate for the variableconditions met within overhead trolleyconstructions, thereby permittingproper positioning of the trolley Wires.

Other objects and advantageswill appear `from the following description.

In the accompanying drawing illustrating my invention: y d

Fig. 1 is a side view in partial section of my invention arranged tosupport two trolley wires.

Fig. 2 is a view in partial section of the end cap I use beforeapplication to the connecting bar.

Fig. 3 is a side view showing a portion of the end cap in Fig. 2. y

Fig, 4 is a side view of the adjustable arm I employ.

Fig. 5 is an edge view of Fig. 4.

Fig. 6 is a side view of a special bolt I use` Fig. '7 is an end view ofFig; 6.

My improved hanger is so constructed that variation in the spanwiresoused to support the trolley wires, may be easily adjusted suchthat the trolley wires may be installed and maintained in a horizontalplane at the hanger.

Sometimes the span wires to a hanger are of equal length and sometimesof greatly different lengths and often the `far end of one span Wire isattached to its support at a greater height than that of the other spanwire. My invention will make it possible to compensate for suchvariations.

In the preferred embodiment of my invention I provide a connecting bar Iof necessary length whereby the end members 2 may be held in spaced iand insulated relation.

The member I may be of wood or of other approved construction ormaterial. I prefer wood as it has been found dependable and economical.

The end members 2 are cup shaped as shown in Fig. 2 with projecting lugs3 and 4 forming therebetween the space 5. Both lugs 3 and 4 are providedwith registering openings 6 and 'I. The opening 1 is surrounded by aplurality of serrations 8.

The cup shaped member 2 originally and the `ends of the bar I have headswith tapered side Walls and when the members 2 are positioned on theends of the bar l and the side walls of the member 2 forced inwardly,a

v connection is secured which is equal or better than the minimumbreaking strength of the bar.

The arms 9 are secured to the end members 2 in adjustable relationthereto and are so attached to the members `2 that `they may be adjustedin a vertical plane to differ angular posii tions relative to the bar I.

This adjustment is secured by the use of abolt or pintle I0 having theunder surface of its head II provided with serrations I2 to correspondtothe serrations 8 on the end member 2.

The bolt ID is further provided with an outoi-round shank I3,preferably` square, and projecting from the shank I3 is a threadedportionL I4 to take a nut I5.

Between the head II andshank I3 and between To assemble the arms 9 inthe slots scf the end members 2, the arms are first positioned in theslots 5 with the openings 6, 1 and I'I registering. The bolts IIJ arethen positioned in the open-` ings with the serrations I2 on the bolthead `cooperating with the serrations 8 onthe lug 4.`

This locks the arms 9 against pivotal movement about their pivotalcenters which are the axes of the openings 6 and 'I because the ShanksI|3 are sufficiently long to enter Well the openings I'I` in the arms 9.

Since the opening 'I is round, the bolt IIJ is free to rotate in thelugs 3 and 4 when the serrations are not interlocked. i

When the arms 9 are properly positioned as to their angular relation tothe axis of the bar I ,u

then nuts I5 are secured to the projecting ends of the threaded portionsI4, employing a spring lock washer, if desired, to prevent itsunscrewing.

If at any time it is found thatthe sag of the span wires supporting thedevice has changed so serrations and'retighten the nuts I5. d l

has straight sides 5 tive to the longitudinal axis of the body. andmeans to maintain said cooperation between the said one lug and thebolt-like member.

5. An adjustable fitting comprising a metallic member provided withmeans to secure it to a body member and also having two projecting lugsin xed spaced relation and having axially registering openings but oneopening being larger than the other opening, an angularly adjustable armhaving one end pivotally mounted in the space between the lugs, the armhaving an opening through the said one end and registering with theother `said openings, a pintle slidably positioned in the said openings`and having spaced portions rotatable in the rst `said openings relativeto the lugs, means on the pintle intermediate the spaced portionsandother means on the arm arranged to cooperate with the said means onthe pintle to prevent rotation of the pintle relative to the arm, meanson the pintle and means on the outer face of one lug arranged tocooperate with the last said means on the pintle to prevent rotation ofthe arm and pintle relative to the lugs, and means on the pintlecooperating with the outer face of the other lug to prevent the pintlesliding and to maintain the cooperation of the said means on the pintleand on the said one lug after the arm has been angularly adjustedrelative to the lugs.
